ATI YV12 Planar Format CoDec

[zante]

that s the only codec that i got avisynth to work with cce
without having to convertoyv2.
The speed was kind of slow though, like (0.5). I got it through ace codec megapack.Does any one know if this does the job well for the
new avisynth or if has any suggesstions for what to use.
I always did the vfapi thing or hte automated dvd2svcd method with the old avisynth, but i am trying the new cce 2.66.1.7.
the avisynth i use is AviSynth_210103(exe) with MPEG2Dec3 v1.00 on winxp.
thanks

You won't gain anything from using an YV12 codec - the video has to be converted to yuy2, either in AviSynth or in the codec, since CCE doesn't know how to read YV12 or I420.

But please report it here, if you get YV12 to work WITHOUT the codec.

You won't gain anything from using an YV12 codec - the video has to be converted to yuy2But you will gain processing speed in avisynth if you're using YV12 capable filters, right?

I hope there'll be HuffYUV YV12 and MJPEG YV12 available soon...

*Edit* I just saw I got a little off topic here. Now I think I know what both of you meant (better late than never... ;)): CCE can read YV12 output from avisynth 2.5 when the ATI codec is installed - but then it's probably just the codec that converts the YV12 output before CCE is processing it. If the codec wasn't present, this would mean the new CCE could read YV12. Right?

im pretty sure mjpeg already supports yv12, but i may be wrong.

[theReal]

Do you mean it could easily support YV12 (which I also believe), or do you know any MJPEG codec which is supposed to encode and decode to YV12?

I heard that HuffYUV will come with YV12 support soon, but the Picvideo MJPEG codec I'm using does only support YUY2 and RGB.

im not completely sure, but I think morgan mjpeg supports yv12. Yeah and I was reading about the huffyuv yv12 codec, -h was coding it I believe.

If your gonna run an Avisynth 2.5 script in CCE your more than likely better off throwing converttoyuy2() at at the end then using this codec. Best Case thats's what its doing, but since you mentioned low speed i take it you've gotten higher before. Which, leads me to believe its more than likely converting to RGB which is a complete and utter waste.

@digitize: Morgans MJPEG codec is able to "receive" and "send" YV12 but is not storing YV12. The received YV12 is converted to the usual format of an MJPEG codec (even VirtualDubs own routines can read it).

[digitize]

ah, thank you for clarifying (sp?). Well anyway, i hope -h finishes coding the huffyuv yv12 codec.
